From: Randy Dunlap <rdunlap@infradead.org> Drop all context analysis and lock (tracking) attributes to avoid kernel-doc warnings. Documentation/core-api/kref:328: ../include/linux/kref.h:72: WARNING: Invalid C declaration: Expected end of definition. [error at 96] int kref_put_mutex (struct kref *kref, void (*release)(struct kref *kref), struct mutex *mutex) __cond_acquires(true# mutex) ------------------------------------------------------------------------------------------------^ Documentation/core-api/kref:328: ../include/linux/kref.h:94: WARNING: Invalid C declaration: Expected end of definition. [error at 92] int kref_put_lock (struct kref *kref, void (*release)(struct kref *kref), spinlock_t *lock) __cond_acquires(true# lock) --------------------------------------------------------------------------------------------^ The regex is suggested by Mauro; mine was too greedy. Thanks. Updated context analysis and lock macros list provided by PeterZ. Thanks.
